    摘要： The stirring apparatus is an electronic design that generates rotating magnetic fields to drive magnetic stir bars within vials placed above the cover of the stirring apparatus. Below the cover is a magnetics board containing multiple vial groups of four air core coils arranged in rectangular patterns. Each vial group has with two pairs of diagonal coils. The coils in each pair are wired in series and have opposite winding directions. Each pair is driven by a different phase of a stepper motor driver. The vial groups are spaced appropriately for placing one vial above each group. The adjacent coils of adjacent vial groups are driven by the same phase and have the same magnetic direction. The cover contains an array of pole standoffs that matches the coil pattern. The hollow center of each air core coil contains at least a portion of one pole standoff.

    摘要： A vortex generator intended to create a controlled vortex in a fluid medium such as a gas or liquid. The upstream portion of the vortex generator includes an inlet section which directs the fluid into the vortex generator and creates a vortex therein by use of an internal rotational symmetric cavity with a curved geometry. Downstream from the inlet section is a vortex chamber having one of several shapes in which the vortex motion is established. The vortex generator may have one of two shapes, one being a trumpet shape or elongated, and the other being a more ovide or egg shape. Also included is a cavitation assembly at the outlet portion of the vortex generator which creates cavitation.
